To nl @sham it may concern:

Beit known that we, JOHN B. STRAND, JOHN H. HAUGEN, WILLIAM CoEsrsLD, and GEORGE Frscnp'orr, citizens of the United States of America, and residents of Chicago, in the conliy Cook and State of Illinois,

have invented certain newand useful Improvenierrts in Sofa-Beds, of which the fol- Owing 'is 'a specifica-tion j yThis invention relates to that type of sofa beds which constitute the subject matter of- Letters Patent No.' 816,134 issued March 27 1906, to John B. Strand and John H. Haugen for improvements in sofa beds. And the present improvement has for its various i-'objectsz to provide. a simple and effective connection between the -reversible sofa bed `jmember and its stationary supporting frame,

and by which said reversible section is held and guided in its turnin movements, and such movements attains with the exertion .of but little iorcegto provide a simple and elicient structural formation and combinai hinged secti tion of parts in a folding bed frame carried by said reversible section, and in which the of said bed frame are auto'- maticajlly brought into an elevated and even plane, as said sections areopened to form vthe bed surface and with a corresponding automatic descent of said sections as they are vclosed to et'ier after use as a bed; and also toprovi e means for locking the reversible sofa-bed section in its bed position against accidental turning, all as will, lhereinafter more fully appear. n In the accompanying drawings illustrativel of the present invention: Figure 1 is'a vertical sectional elevation on line awe' Fig 2, with the reversible sofa-bed sectionshoivn in dotted lines in its sofa forming positionf* in :its open or unfolded condition. Fi 1l or folded condition. Fig. 12 is a detail longitudinal section on line ac3-x8 Fig. 10. Fig. 13 is a detail transverse section on line no4-n4 Fig. l2.

Similar. numerals of reference indicate likeI parts in the several views. y

Referring to the drawings, l represents the upright back member, and 2 the upright end members secured rigidlT together to constitute the main stationarv supporting frame or Setion of the sofa-bed.

3 is the reversible sofa-bed section secured to the aforesaid main frame in the pivotal and adjustable manner hereinafter described, and capable of a semi-rotation so that in one position it lwill constitute the seat portion of the sofa-bed, and inthe other position pre# sent the folding bed frame hereinafter described, and which bed irarne is adapted to be unfolded to present ample bed surface.

4 are radius-links pivotally secured near ,I

the rear of'their points of pivotalattachment and are connected to one en d of the tension springs'- 5, ythe opposite ends of said sV rings being attached to the main sofefbed' eme.

Such springs are adapted to impartacon-- stant upward stress "u on the Aforward ends ,of the radius-linlrs, wit a View to aid in the movement of the reversible bed section from a sofa to ay bed position.v lThe forward ends Vof such radius-links are formed'withmpentop recessesf adapted for pivotal 'engagement with lateral studs v7 in the end-.boards -11 ofthe reversible sofa bed member 3, about the midwidthof the sam`e Such lateral studsare' adaptedto rest upon the tracks hereinafter described, to aid in the support of the reversible member 3, aforesaid. Such open top recesses 6 permit ol a ready disconnectionof the radius-links from the studs 7, in the operation of dismemberingthe bed `for shipn'ient and other purposes, as Well as an operative cohnecti of the appliances in an assemblage of the 'sofa-bed parte.

8 are tracks orslideways carried on the inner l:faces of the end members 2. of the main lframe; such tracks-are preferably inclined from the horizontal and in adownward direction towards the rear of the mam frame, asshown H1 Flgsjl and 3, and as 1n the before f mentioned patent No. 816,134, to attain a low position of the reversible bed member when the article is arranged as a sofa, and an elevated position of the reversible member when the article is arranged as a bed. i

9 are track wheelsv engaging the tracks or slideways 8, and secured'to the respective ends of the reversible member 3, at points removed from the lateral studs 7 before described, and as shown in Figs. 1 and 3.

The operation of the parts above described, are similar to that in the aforesaid Letters Patent No. 816,134, and is as follows: In changing from a sofa to a bed form of .the article, an upward pull is made on the lower and forward edge of the reversiblemember 3, to tilt the same upwards with the track wheels 9 as a fulcrum and the radius-links 4 acting as a restraining means to prevent any independent movement of the ends of the reversible member. Vith the progress of such tilting movement the track.wlic.els 9 move forward on the tracks 8, the forward ends of the radius links 4 moving upwards in consonance with such forward movement of the track wheels. Such forward movement of the track wheels continue until a full half turn has been imparted to the reversible member, with the attainment of such half turn the track wheels are at the forward ends of the tracks and the radius links have returned to their original position and in contact with the tracks, to constitute in connection with the track wheels the entire supporting connection between the reversible member and its stationary supporting frame.V In changing the article back again from a bed to a sofa form the reverse of the above described operations will take place.

In the present construction the reversible member 3 is of a shell form, and comprises a horizontal member 10, the exposed surface of which is upholstered to form a sofa seat; a

Apair of vertical end boards or members 11,

and a vertical longitudinal board or member 12, shown in Figs. 4,5,6, 7, 8, 9, 10 and 11, and as so constructed provides a receiving chamber for the folding bed frame now to be described.

13 is a longitudinal rail adapted to be secured to the reversible member 3, in manner hereinafter described, andprovided at its respective ends with pivot brackets 14 to whichY are pivotally attached the folding frame hercinafter described, by elongated pivot pins or pintles 15.

In the present construction the pintles 15 are formed with headed outer ends adapted for insertion in angular recesses 16 in catch plates 17 secured to the end boards 11 ofthe reversible member 3, as shown more particularly in Figs. 12 and 13; the construction is such that said.. outel` ends of tlie pintles will be initially introduced into said angular recesses i16, after which the longitudinal rail 13 will be pushed into place on the horizontal board 10 of the reversible member 3, and secured in place by a thumb-screw 18 or lik/e fastening, see Figs. 4, 5, 6 and 7, to afford a substantial connection of said rail in place, and at the same t'me' permit of aready detachment thereof i'dhendesired.

19 areT shaped links pivoted intermediate lbf their lengths and by their laterally e.' ending arms 20, to the brackets 14, by ther foresaid pintles 15. 'l I 21 and 22 are counterpart skeleton frame sections ivotally connected to the opposite ends of t e aforesaid links 19 by hinge connections which permit of an independent quarter turn between the arts when they are moved into their foldedlfor uhfolded positions as hereinafter more yfully set forth:

The aforesaid frame members 21 and 22, and

ntermediate links 19 constitute a marginal supporting frame to which is attached any suitable elastic webbing, (not-shown), and generally employed in sofa beds as the suport for the ordinary bed mattress; in the folded condition of said arts, illustrated in Fig. 4, the mattresswill e inclosed by said parts as usual.

23 are pull bars pivotally connected to the gull p bars 23, as illustrated in Figs. 4, 5, 6 an 7.v

With thc described construction of folding bed frame, and in the unfolding movement of the saine the following operations take lace serially The operator pulling upward y on the free end of theI uppermost frame section 21, moves the same into the vertical osition shown in Fig. 5, without all'ccting t e position of the othe.' parts of the bed frame.l

Further outward and downward pulling by the operator upon such free end of the uppermost members 2l gradually tilts the lntermediate links 19 from their previous vertical osition into a horizontal position, and said links in turn and in a direct manner and through the instrumentality of the pull bars 23, levers 24 and tracks 25 lifts the lowermost frame member 22 into an elevated plane .level with that of the uppermost frame member 21 and links 19. The various positions of the )arts in the unfolding movements above described are serially.illustrated in Figs. 4, 5, 6 and 7. In a fo ding movement of the bed frame. thc reverse. of the above described operations take place. n

26 area pair of vertically'arrangedv shafts journaled on the longitudinal board of the reversible member 3, and provided with crank shown in Fig. 4.

esmas arms 27 and '28 at their' respective upper and lower ends. as shown in Figs. 4, 5, 6, 7, 8 and 9. In one position of said shafts the uppermost crank arm 27 is adapted to engage over the uppermost frame section 21 before described, to hold the same in place in the folded condition of the bed frame, and as In theother position of said shafts, said uppermost frame section 22 is released and free to be opened, and at the same time. the lower crank arms 28 are adapted `to lock the reversible member 3 to the main frame to prevent independent action between said`parts, and to suchend said crank arms 28 are o cratively connected to latch bolts 29 guided in the reversible member 3, and engaging in kee er orifices 30 in the main frame, as illustrate in Figs. 8 yand 9.

81 are hingedlegs carried lon the outer ends of the uppermost bed frame Asection 21, and adapted to support the same in-its unfolded position for use as a bed.
